Sulfoaluminate cement, non-ionic polyacrylamide and sulfamate high-effective water reducing agent were used as main raw materials to fabricate concrete. The adhesive performance of high performance sulfoaluminate cement underwater non-dispersed concrete and its influence on water quality in surrounding water areas were studied. The compressive strength ratio of concrete cast in water and in air was also determined. The results show that mortar and concrete using non-ionic polyacrylamide as adhesion agent has many advantages such as superior underwater anti-washout properties, little pollution to water quality in the surrounding water areas and obvious early strength. Furthermore, the compressive strength ratio of concrete cast in water and in air is also up to the required standard. |
